Endpoint Data Loss Prevention — Endpoint DLP now supports a pre curated list of file extensions for the file extension condition

Why it matters: Upcoming change

Endpoint DLP now includes a pre curated list of file extensions for the file extension condition. Previously, file extensions were entered as free form text, which could result in unsupported or non-scannable extensions being used. This could lead to gaps in protection and increase processing overhead on endpoints. With the pre curated list, you can select only supported file extensions. This helps improve policy reliability and reduces unnecessary processing on endpoints.
